I am trying to track an object with opencv and publish the center of rectangle to a ROS topic in Rust.
My Cargo.toml looks like this:
[package]
name = "test_package"
version = "0.1.0"
edition = "2021"
# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html
[dependencies]
opencv = "0.86.1"
r2r = "0.8.0"
when I cargo build, it fails to build the packages
The error looks like this:
error: failed to run custom build command for `opencv v0.86.1`
Caused by:
process didn't exit successfully: `/home/light/test_package/target/debug/build/opencv-27479df15cc97d32/build-script-build` (exit status: 101)

I am running ubuntu 22.04 LTS with ROS 2 humble.
To reproduce this run these commands :
$cargo new test_packate
$cd test_package
$cargo add r2r
$cargo add opencv
$cargo build
What is the problem here?
I first didn’t source ROS, then r2r does not build. After sourcing ROS, opencv does not build.
opencv and r2r build properly when I don’t depend on both of them. When I depend on only one of them separately it works.
Did you Make sure the supported OpenCV version (3.4 or 4.x) and Clang (part of LLVM, needed for automatic binding generation) are installed in your system.?
Thank you. I totally missed the readme in github. There is a paragraph for this exact problem lol
You’re very welcome. For further reading: that was a build script error. If you see more errors formatted similarly, you’ll at least know where to investigate.
